Good day! Based on your request for an eyepiece or finder scope for a Powerseeker 70 AZ telescope, I would recommend the following options available in Cape Town: The Celestron Omni eyepieces ranging from 6mm to 15mm for R2059 each would be a great choice as these are specifically designed for 1.25" telescope eyepieces and come highly rated. They will provide different magnifications to suit various observing needs. For a finder scope, the Astronomical Telescope 8-24MM zoom eyepiece for R589 could work well as it will allow you to easily adjust the magnification for locating targets. Both of these options are well within your budget and available locally. Please let me know if you need any other details. I hope this help you find a suitable accessory for your telescope.
